Abstract

In the present study, the air-side heat transfer and pressure drop characteristics of the fin-tube and PF heat exchangers have been experimentally investigated under the cooling standard condition. Fin type of PF heat exchanger is a triangler and squarer form. The experimental data of the slit fin-tube and two kinds of PF heat exchangers are measured using the air-enthalpy calorimeter and the constant temperature water bath. As the inlet air velocity increases, the heat transfer rate and pressure drop of the heat exchanger increased. The heat transfer rate and pressure drop of PF-2 heat exchanger of the squarer fin is larger than that of PF-1 heat exchanger of the triangler fin. As the inlet air temperature increases, the heat transfer rate decreases and the pressure drop is nearly uniform.
